Ford F-350 Ignition Conversion Kits
Ford F-350 Ignition conversion kits
Starting at $248.95, AutoBuffy stocks 2 ignition conversion kits from Standard Ignition for the Ford F-350. An ignition conversion kit replaces a worn or outdated points-based ignition system with a modern electronic one, delivering stronger spark, more consistent timing, and better fuel combustion. When the original system fails, you get hard starts, misfires, and poor fuel economy.
Signs your Ford F-350 needs a new ignition conversion kit
- Hard starting or extended cranking before the engine catches, especially when cold
- Rough idle or engine stumble that worsens as the distributor points wear and timing drifts
- Frequent misfires under load or at highway speeds due to weak or inconsistent spark
- Noticeably reduced fuel economy as incomplete combustion wastes fuel
- Engine hesitation or flat spots during acceleration caused by erratic timing advance
- Distributor points require repeated adjustment or replacement every few thousand miles
Which ignition conversion kit should you buy for your Ford F-350?
The main decision is choosing between a basic electronic points-replacement module and a full distributor conversion with integrated ignition control. Consider whether you want a drop-in solution that reuses your existing distributor cap and rotor, or a complete system that upgrades the distributor, coil, and wiring harness together. Your engine's intended use — stock street driving versus performance — should guide how comprehensive a kit you need.
Electronic Points Replacement Module
Best for
Budget-conscious drivers who want a simple, reversible upgrade
What you get
A solid-state trigger that mounts inside the existing distributor, eliminating contact points while keeping the original cap, rotor, and coil
Complete Electronic Distributor Conversion Kit
Best for
Owners doing a full ignition refresh or chasing reliable daily performance
What you get
New or remanufactured distributor with built-in electronic trigger, matched coil, cap, rotor, and all wiring connectors
High-Energy Ignition (HEI) Conversion Kit
Best for
Performance builds or engines with high-compression or larger-displacement modifications
What you get
Single-unit HEI distributor with internal coil and module, high-output spark, and simplified wiring — eliminates external ballast resistor
Pertronix-Style Magnetic Trigger Kit
Best for
Classic and vintage vehicle restorers who want an invisible, stock-appearing conversion
What you get
Precision magnetic impulse ring and solid-state module that fit entirely inside the stock distributor housing with no external changes

Replacing an ignition conversion kit on a Ford F-350
Moderate⏱ 1–3 hoursTiming lightDistributor wrench or socket setScrewdrivers (flathead and Phillips)MultimeterMarker or tape for labeling wires
Begin by disconnecting the battery and carefully labeling all ignition wiring before removal. Follow the kit manufacturer's instructions to mount the electronic trigger or swap the distributor, then reconnect wiring to the coil and any ballast resistor as specified — HEI conversions often eliminate the ballast resistor entirely. After installation, use a timing light to set base timing and verify smooth idle before returning the vehicle to service.
Frequently asked questions
How much does it cost to replace ignition conversion kits on a Ford F-350?
Parts start at $248.95 for the Ford F-350. A basic electronic module is the least expensive route, while a full HEI or complete distributor conversion kit costs more but requires fewer future purchases. Professional installation adds labor cost, though many owners with moderate mechanical experience complete this job themselves in a couple of hours.
Will an ignition conversion kit improve performance on my Ford F-350?
Yes, in most cases. Converting from points to electronic ignition delivers a stronger, more consistent spark at all RPMs. You can expect easier cold starts, smoother idle, better throttle response, and modest fuel economy gains. The improvement is most noticeable on engines that were running degraded or out-of-adjustment points ignition systems.
Is an ignition conversion kit reversible on a Ford F-350?
A basic points-replacement module is reversible — the original points and condenser can be reinstalled in minutes. A full distributor swap or HEI conversion is technically reversible but requires keeping the original distributor in storage. Most owners who complete a full conversion never go back, as the reliability improvement is significant.
Do I need to replace the coil when installing an ignition conversion kit on my Ford F-350?
It depends on the kit. A simple points-replacement module often works with the existing coil, though a fresh coil improves results. Full conversion kits and HEI systems typically include a matched coil or have one built into the distributor cap. Always verify coil compatibility with the kit manufacturer before reusing the original coil.
Does an ignition conversion kit require tuning or timing adjustment on a Ford F-350?
Yes. After installing any ignition conversion kit, you should set the base ignition timing with a timing light. Electronic systems hold timing more precisely than points, so the engine often responds well to a small timing advance adjustment post-install. Refer to your engine's recommended base timing specification and confirm with a timing light before driving.
How long does an electronic ignition conversion kit last compared to points on a Ford F-350?
Electronic ignition modules have no mechanical contact wear, so they routinely last the life of the vehicle with minimal maintenance. Traditional breaker points typically require inspection and adjustment every several thousand miles and periodic replacement. Converting to electronic ignition essentially eliminates points-related maintenance intervals from your service schedule.
